How to Choose the Correct HDMI Port for Gaming

Maximize gaming performance by identifying and selecting the correct HDMI 2.1 ports for 4K 120Hz support on your display.

1. Inspect the display labels. Locate the HDMI inputs on the back or side of your television. Look for ports labeled 'HDMI 2.1', '120Hz', or '4K/120'. If ports are not explicitly labeled, consult the printed manual or the manufacturer support page for your specific model number.
2. Utilize an Ultra High Speed HDMI cable. Verify your HDMI cable is marked 'Ultra High Speed'. This certification ensures the cable can handle the 48Gbps bandwidth necessary for high-resolution, high-refresh-rate gaming. Connect one end to the identified HDMI 2.1 port and the other to your console or GPU.
3. Enable HDMI Enhanced Format. Navigate to the TV settings menu using your remote. Locate the 'Inputs' or 'External Inputs' section and select 'HDMI Signal Format'. Switch the setting to 'Enhanced Format' or 'VRR Mode' to allow the port to receive the full bandwidth signal.
4. Confirm output on the console. Access the 'Video Output' settings on your gaming console. Ensure '4K Transfer Rate' is set to 'Automatic' or 'Enable' and check that the 'VRR' (Variable Refresh Rate) setting is toggled to 'Automatic'. The system will now verify the handshake with the television.
5. Run a system diagnostic test. Select 'Video Output Information' within the console settings menu. Confirm the 'Supported Frequencies' list includes '120Hz' and that 'VRR' is active. This confirms the link between the specific HDMI port and the console is functioning at maximum specifications.
